Weather Alert Scan (In the USA)
This feature allows you to check the Weather Broadcast Memory Channels
for the presence of the NOAA Alert Tone while operating using VFO scan or
Memory channel scan.
When the Weather Alert Scan feature is engaged, the
FT-4VR/VE
will check
the Weather Broadcast Channels for activity every five seconds while scan-
ning. If you watch the display carefully, you'll observe the scanner periodically
shifting to the Weather Broadcast channel, scanning the Weather channels
quickly in search of the Alert Tone, after which regular scanning will resume
for another five seconds.
